Examples of UnionTypeInfo

org.apache.hadoop.hive.serde2.typeinfo.UnionTypeInfo
UnionTypeInfo represents the TypeInfo of an union. A union holds only one field of the specified fields at any point of time. The fields, a Union can hold, can have the same or different TypeInfo. Always use the TypeInfoFactory to create new TypeInfo objects, instead of directly creating an instance of this class.
